Utilize tcpdump a potent data-network packet analyzer, to gather network packets effectively. This tool permits packet filtering for precise collection. To explore the available options, refer to the main page of tcpdump. Here's how to run it with superuser privileges:

# tcpdump -i eth0 -w mycap.pcap

Alternatively, you can opt for the Wireshark sniffer as well.

Please note that you should set up appropriate permissions on the pcap file then.
